Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027390, here are decompositions:

59 + 1027331 = 1027390
71 + 1027319 = 1027390
101 + 1027289 = 1027390
113 + 1027277 = 1027390
149 + 1027241 = 1027390
167 + 1027223 = 1027390
179 + 1027211 = 1027390
191 + 1027199 = 1027390

Showing the first eight; more decompositions exist.
